       3. The combination padlock according to  claim 2 , wherein when the flat spot contacts one of the corresponding at least on faulty gates the faulty gate stops the clutch from rotating so that the smooth slope-edge smoothly allows the extended-fin to slide away from the faulty gates and the true gates. 
     
     
       4. The combination padlock according to  claim 1 , wherein the at least one true gate forms a passage through the body for the corresponding at least one extended fin for each clutch, and the at least one faulty gate does not form a passage through the body for the corresponding at least one extended fin for each clutch. 
     
     
       5. The combination padlock according to  claim 1 , wherein each dial of the plurality dials contain a plurality of teeth to engage the at least one extended fin of each corresponding clutch. 
     
     
       6. The combination padlock according to  claim 1 , wherein each clutch of the plurality of clutches comprises a clutch hole to allow insertion of the spindle through each clutch, and the combination padlock further comprises a pair of C-Clips configured to retain the plurality of clutches on the spindle so as to form an assembled spindle in which movement of the plurality of clutches is controlled by movement of the spindle. 
     
     
       7. The combination padlock according to  claim 6 , wherein the assembled spindle controls the movement of the locking bolt and locking ball to further control the movement of the shackle between a lock open state in an unlocked by combination mode and a locked mode state in a locked mode. 
     
     
       8. The combination padlock according to  claim 7 , wherein the shackle neck is configured to receive the locking ball when the combination padlock is in the locked mode and the locking bolt is configured to retain the locking ball in the shackle neck in the locked mode. 
     
     
       9. The combination padlock according to  claim 1 , wherein when at least one of the lock open combination digits is not selected for at least one of the dials of the plurality of dials each of the clutches corresponding to the at least one of the dials not having the lock open combination digit selected prevents the combination padlock from being operated from a locked mode to an unlocked by combination mode, and
 wherein in the locked mode of the combination padlock rectilinear movement of the spindle within the body away from the locking bolt neck of the locking bolt is prevented. 
 
     
     
       10. The combination padlock according to  claim 9 , wherein the spindle comprises a tail configured for engagement with the locking bolt neck in the locked mode of the combination padlock,
 wherein the combination padlock further comprises a shackle spring configured to urge the shackle in a direction substantially perpendicular to the movement of the locking bolt within the body and substantially parallel to the movement of the spindle within the body, and 
 wherein when all of the at least one extended fins for each clutch of the plurality of clutches are fully aligned with the true gates, the spindle is configured for operation so that the tail of the spindle moves away from the locking bolt neck of the locking bolt so that the shackle spring urges movement the shackle so that the shackle neck moves the locking-ball away from the shackle neck so as to operate the combination padlock into the unlocked by combination mode. 
 
     
     
       11. The combination padlock according to  claim 9 , wherein the spindle comprises a tail configured for engagement with the locking bolt neck in the locked mode of the combination padlock,
 wherein when all of the at least one extended fins for each clutch of the plurality of clutches are fully aligned with the true gates, the spindle is configured for operation so that the tail of the spindle moves away from the locking bolt neck of the locking bolt, 
 wherein the shackle neck is configured to urge the locking ball away from the shackle when the tail of the spindle moves away from the locking bolt neck of the locking bolt, and 
 wherein when the locking ball is disengaged from the shackle neck the combination padlock may be operated into the unlocked by combination mode. 
 
     
     
       12. The combination padlock according to  claim 1 , wherein the at least one slope edge for each of the at least one extended fin for each clutch are rounded slope edges. 
     
     
       13. The combination padlock according to  claim 12 , wherein the at least on faulty gates formed in the body are configured to allow the at least one extended fin of each clutch to contact at least one round edge of the extended fins and forceably slide away from the faulty gates when contacting edges of the faulty gates. 
     
     
       14. The combination padlock according to  claim 13 , wherein there is a flat spot on the at least one extended fin of each clutch so that when the flat spot contacts one of the corresponding at least one faulty gates the flat spot with the faulty gate of the corresponding at least one faulty gates to cause a clicking sound. 
     
     
       15. The combination padlock according to  claim 13 , wherein the extended fin round edge allows the extended fin to slide away from the faulty gate to protect against lock picking.
